I have just bought a Silvergen machine and am new to CS making.....question:   
when I am finished making the CS it says to wipe off the silver strips...  I 
notice that it does not all come off.....I have only made the CS twice......do 
I need to scrub the strips until they are a clean silver look or just wipe them 
off and continue.......

Tks,

Kathy Neff
